IMPROVEMENT lN SHlNGLlNG-BRACKETS.

Specification forming part of Letters Patent No. 163,587, dated 25,1875; application filed March 11,1875.

To all whom it may concern Be it known that I, ALFRED P. FLnToHER, ofMiddletown, county of Middlesex and State of Connecticut, have inventedan Improved Staging-Bracket, of which the following is a specification,reference being had to the ac companying drawings, forming part of thesame.

My invention relates to a bracket to support stagings employed inshingling the roofs of buildings, and for other similar purposes andconsists in a slotted brace or tie pivoted to the horizontal beam orsupport upon which the staging is laid, and a slotted upright, hinged atits upper end to the rearend of the said beam, to which upright the saidbrace or tie is secured and adjusted by a screw-bolt and thumb-nutworking in the slotted openings in the brace and upright, and saidupright having feet provided with claws at its lower end, the forwardend of the brace and beam, beyond their pivotal point, being formed,respectively, into an upper and lower jaw,

provided with teeth, the lower jaw, carried by the beam, being curved,and the upper jaw, carried by the brace, being flattened, so that itsupper side forms a portion of the level support for the staging, thesaid beam being provided with'a sliding collar, secured in place upon itby a thumb-screw, whereby the bracket may be readily adjusted to anyslant of roof,

and, when thus adjusted, held securely in place upon the roof, and forma level support for the staging, and whereby the staging will beprevented from sliding or iallin g from the bracket.

Figure 1 is a side elevation of a bracket embodying my invention,showingit adjusted and secured as a support for staging upon a slantingshingle-roof. Fig. 2 is a rear elevation of the same. Fig. 3 is a frontelevation of the jaws formed by the forward ends of the beam and brace.

Ais the brace or tie, having the slotted opening a, and is pivoted atbto the beam B, upon which the staging S is laid. C is the upright,having the slotted opening a, and provided with the claws d d upon thefeet D D, respectively, at its lower end, and hinged at its upper end tothe rear end of the beam B at e,

as shown. E is a screw-bolt, provided with a thumb-nut, F, and a washer,20, arranged to work in the slotted openings to and c of the brace A andupright C, and opera-ting to secure the brace firmly to the upright atany desired angle. The forward end of the beam B is formed into thelower curved jaw f provided with teeth, as shown, and the forward end ofthe braceAis bent into the straight or flattened jaw g, which is alsoprovided with teeth, as shown, so that the upper side of the jaw g is ina line with the upper side of the beam B, and forms a portion of thelevel support for the staging. m is a collar arranged to slide upon thebeam B, and formed with the projection 19 upon its upper side, and heldat any desired place upon the beam by the thumbscrew n, and operates toprevent the staging from sliding or falling off of the bracket.

I make the various parts of my bracket, as described, preferably ofcast, wrought, or malleable iron.

Now, it is evident that by the operation of the screw-bolt E andthumb-nut F, and the slotted openings aandc in the brace A, and theupright C, the bracket may be adjusted to the angle of slant of theroof, and held in position, so that the beam B and the upper side of thejaw 9 will form a level support for the staging, and that the bracket,thus arranged and adjusted, will be attached securely to, and held inposition upon, the roof, as a support for stagings, by the operation ofthe jaws f and g, griped upon the lower portion of a shingle nailed inplace upon the roof, as shown in the drawings, or upon any otherconvenient and suitable object, and, by the claws d d of the feet D D ofthe upright C, fixed in the surface of the roof, as shown.

I do not claim, broadly, a bracket for staging consisting of asupporting-beam and upright, and a brace, and the devices shown forsecuring the bracket upon the roof, intending to limit myself to thecombination, with the parts herein shown and described, of the brace A,having the slotted 'opening a, and the upright C, having the slottedopening 0, together with the screw-bolt E, the thumb-nut F, and thewasher 10.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination, in a staging bracket, of the slotted brace A, pivotedto the beam B at 1),"0116 toothed jaws f and g, the jaw f carried by thebeam B being curved, and the jaw 9 carried by the brace A beingflattened, so that its upper side will form a portion of the levelsupport for the staging when adjusted in po sition upon the roof, theslotted upright 0 provided. at its lower end with the claws d d upon thefeet D D and hinged at e to the beam B, the screw-bolt E, the thumb-nutF, and the washer w, and the collar m, formed with the projections 19,and provided with the thumb screw 42, as described. v
